A.M.
Dawn P hit the nail on the head regarding the nap - don't cut out the nap. It will not help and it will make things worse - being overtired is a vicious cycle. Talk to your pediatrician to rule out any medical reasons, but I would really just try and get her bedtime routine going early so that she is in bed by 6:30p or 7:00p and hopefully you can turn it around. Definitely check to see if she's cutting her molars as they are painful and take quite a long time to erupt and that pain definitely interrupts sleep patterns. If you can, try to nap while your daughter naps for a few days to catch up on your own sleep - sleep deprivation does make you feel awful, physically. Can anyone come over and watch her for a few hours while you sleep if it doesn't work out that you can nap while she naps? I'm so sorry. Good luck!
